Have a nice 58 F100, big back window I took from Maine to Ohio last shootout, very little rust, only front fender bottoms, made it there and back no problems but I know nothing about the motor, it came originally in my 55 Victoria and has lots of miles, but still goes and doesn't leak. truck has original paint on it, so has never been hacked up, bed is mint, (long bed) for the price I should be able to get more for the bed than the whole truck.
Where are you located?
